78 is a series system as OE. I'd definitely do the conversion to the parallel pencil type plugs. Starting is much easier with the pencil plugs. More heat goes into the cylinders. Well worth it. A simple conversion. Remove the final ground wire, Attach the hot wire to the first pencil plug. Use jumper wires to connect to each subsequent plug.
Plugs from 82 and 78 are not interchangeable. The threads are different sizes. That's why you have to get the special pencil plugs for the earlier series thread style.
